Thnx all
for sharing views.
It appeared something much interesting as i didn't know any such trials done even for demo sake. Couldn't locate any similar over the 'net too. Separate cases or forced induction is preferred allover.
I learn that though possible to run such configuration it is not worth the effort in terms of output. I might sound stupid but lets pls consider this as a topic of academic interest. hope we can discuss possibly a few options (if any) which may improvise the setup to keep it atleast good as original single. And I would like to try deriving engine character from these.
Big Q: Would this second cyl possibly become parasitic load?
I presume that lower case pumping is suffered mostly by front cylinder taking that engine spins clockwise viewed from RH / carb side. it gets less gas. Can this be countered by a tighter combustion chamber?
And yes the angle seems 60 deg from pic.
